Grille mould manufacturing workflow

  1. Input check: CAD/2D, appearance spec, resin, expected volume, target press.
  2. DFM review: split line, draft, clip/undercut strategy, texture plan, gating & venting.
  3. Mould design: cooling layout, ejection, steel/inserts, wear parts, parting & sealing.
  4. Machining: CNC/EDM, heat treatment, polishing/texture, assembly.
  5. T0/T1 trials: sample parts + photos/video + key dimensions + issues list + action plan.
  6. Approval & shipment: final samples, packing, export documents.

Common grille mould design considerations

Gating & weld lines

  • Keep weld lines away from emblem areas and high-visibility ribs
  • Balance flow to prevent short shots in thin lattice patterns
  • Cold slug / filter strategy to protect cosmetic surfaces

Warpage & flatness

  • Uniform wall with controlled ribs to reduce sink and twist
  • Cooling symmetry to avoid corner lifting
  • Process window suggestions (packing, melt, mold temp)

Venting

  • Micro-vents on end-of-fill and trapped-gas pockets
  • Prevent burn marks on glossy / textured surfaces
  • Serviceable vent locations for long-term production

Ejection & part handling

  • Ejector layout to protect thin ribs and clips
  • Avoid witness marks on show surfaces
  • Optional handling/packing recommendations for deformation control

FAQ — Automotive grille moulds

What grille types can you support?

We support center grilles, grille frames, emblem bases, air intake trims, and related front-end decorative components for passenger cars and SUVs. Share your CAD + appearance class and we will confirm the optimal split, gating, and texture plan.

What is typical lead time for a custom grille mould?

Typical timing depends on size and surface requirement. A practical range is 45–75 days including DFM, machining, assembly, and T0 trials. If you have a fixed SOP date, we can propose a fast-track plan based on complexity.

Which steels and surface finishes do you recommend?

Steel and polishing/texture depend on the surface class, resin (including fillers), and expected shot life. For high-cosmetic areas, we plan polishing/texture processes early to minimize rework after trials.

How do you control warpage on large grille frames?

We address warpage by balancing cooling, optimizing rib ratios, using stable gating, and defining an appropriate process window during trials. We also recommend fixture/packing methods when needed to reduce post-mold deformation.

Do you provide sampling reports?

Yes. Trial deliverables can include key dimensions, photos/videos, defect notes (sink, weld lines, burn marks, flash), and corrective actions for the next trial stage.
